"In addition, a correct reading of the attached thread about the exploding Arty. Luger clearly indicates a poor "gunsmithing" job and not an ammunition problem."
I really can't agree with your conclusion here, but people often reach different conclusions given the same or simmilar facts.
"I will continue to use WWB in my Lugers, as they function 100%with that, but I would not hesitate to use the PRC 124 grain FMJ in any of my 9mm pistols."
It's your Luger, not mine.

Dear JonnyC:
Santa brought me a new chronograph for Christmas, so when I'm in Florida next month, I'll try to confirm your findings. I am shooting the Norinco Red box, you didn't mention just what you were shooting above, as there may be substantial differences in the different types of ammo manufactured by Norinco.
What I did experience with the Norinco Red Box was severe breech-block slap. This is when the rear of the breech-block, where the firing pin retainer is, slaps against the rear frame of the Luger. The slap was quite severe in that it made a deep impression on the surface of the frame (breech-block is hardened, frame is soft). The pistol practically jumped out of my hand!
Breech-block slap is among the main reasons for Luger mechanical failure. None of the American made 9mm I've used in the past ever did this! After the first magazine, I retired the red box to my gun room for use in one of my other 9mm pistols.
It's noon here and only 19 degrees. This is about 10 degrees cooler than normal.
